Volkswagen Group develops complete drive system for electric cars

Volkswagen Group develops complete drive system for electric cars. The development of a complete drive offers efficiency and cost advantages, up to 20 percent more efficiency through the optimal combination of individual components.

During the Tech Day 2023 in Barcelona, the Volkswagen Group Technology provided an outlook of upcoming electric car innovations in the areas of batteries, charging and electronic components. The focus was on the electric drive system of the future. For this purpose, Volkswagen is taking care of all the central components itself and, in addition to batteries and electric motors, is now developing pulse inverters and thermal management systems internally.

The Volkswagen drive system coming from one source offers significant efficiency and cost advantages: up to 20 percent more efficiency is possible through the optimal combination of individual components alone.

Oliver Blume, Chair of the Board of Management of the Volkswagen Group, said: “The Volkswagen Group and its brands stand for first-class products and technologies. Thanks to the size and breadth of the Group, as well as our in-house expertise, we can leverage enormous economies of scale. This benefits our customers and makes our vehicles even better.”

“Designed by Volkswagen”: Pulse inverters and thermal management systems

The pulse inverter is the brain of the electric drive train and is largely responsible for efficiency and performance. For the first pulse inverter to be “designed by Volkswagen”, the developers of these core components redesigned the hardware and software from the ground up. Thanks to the modular toolkit principle, this can be implemented in everything from entry-level engines to sports cars with an output of over 500 kW and more in future. The technology is currently being developed for series production maturity and can already be used with the next MEB generation.

When it comes to thermal management systems, Volkswagen is working on entirely new solutions. While today a large number of individual modules and long hose connections are used, in future these will be replaced with an extremely compact, integrated thermal module. This will control the entire air conditioning, including for the high-voltage battery, and thus will have a major impact on the vehicle’s range and fast-charging capability. The new all-in-one module is also significantly lighter, more robust and more efficient than current systems.

In addition to efficiency, the main focus of the development of all central electric drive components is scalability – because high economies of scale reduce costs.

Group Technology: The technology powerhouse of the Group

Volkswagen Group Technology bundles Group-wide activities in the areas of batteries, charging and electric components and supports the and supports the brands as a group-wide technology supplier. The subsidiaries PowerCo (batteries) and Elli (charging and energy) are also involved here.

Among other things, the high-tech portfolio comprises the unified cell, which will be utilised in all Volkswagen Group vehicles as of 2025 and will set a new benchmark in terms of battery technology. The division also includes the Platform Business, which covers cooperation with external partners like Ford and Mahindra. Around the world, Volkswagen Group Technology employs around 70,000 people.
